EDGAR SHERMAN AR-15 Fine Grip Black Matte. The Granite Grip leverages MJF 3D printing technology with durable nylon 12, akin to our enhanced foregrips for M-LOK or picatinny mounts. Unlike traditional injection molding, this method allows us to bypass constraints like draft angles, enabling the creation of intricate shapes and textures. This flexibility has empowered us to reimagine traditional pistol grip designs. The Granite Grip features a widened geometry that comfortably fills your palm, tapering elegantly towards the bottom. This tapered design enhances hand placement and offers increased leverage and control, optimizing grip performance.
